12 Add a description in the Description tab in the bottom half of the screen.
For example, type The email address of the person to notify.
13 Click the Properties tab for (string)toAddress.
14 Right-click the Properties tab and select Add Property > Mandatory input.
15 Set the value of the Mandatory input property to Yes.
16 Right-click the Properties tab and select Add Property > Matching regular expression.
This property allows you to set constraints on what users can provide as input.
17 Click the Value text box for Matching regular expression and set the constraints to
[a-zA-Z0-9_%-+.]+@[a-zA-Z0-9-.]+\.[a-zA-Z]{2,4}
Setting these constraints limits user input to characters that are appropriate for email addresses. If the user
tries to input any other character for the email address of the recipient when they start the workflow, the
workflow will not start.
You have made both parameters mandatory, defined how the user can select the virtual machine to start, and
limited the characters that can be input for the recipient's email address.
What to do next
You must create the layout, or presentation, of the input parameters dialog box in which users enter a
workflow's input parameter values when they run it.
Set the Layout of the Simple Workflow Example Input Parameters Dialog Box
You create the layout, or presentation, of the input parameters dialog box in the Presentation tab of the
workflow editor. The input parameters dialog box opens when users run a workflow, and is the means by
which users enter the input parameters with which the workflow runs.
The layout you define in the Presentation tab also defines the layout of the input parameter dialog boxes for
workflows you run using a Web view.
Prerequisites
You must have created a workflow, laid out and linked its schema, defined the IN, OUT, and exception
bindings for all elements, and set the attribute and parameter properties.
Procedure
1 Click the Presentation tab in the workflow editor.
2 Right-click the Presentation node in the presentation hierarchical list and select Create display group.
A New Step node and a New Group sub-node appear under the Presentation node.
3 Right-click New Step and select Delete.
Because this workflow only has two parameters, you do not need multiple layers of display sections in
the input parameters dialog box.
4 Double-click New Group to edit the group name and press Enter.
For example, name the display group Virtual Machine.
The text you enter here appears as a heading in the input parameter dialog box when users start the
workflow.
